Their opponents are yet to register a point in this season’s competition, having lost on matchday one at home to Marseilles, but Arsenal will also be eager to claim the three points after their 1-1 draw at Borussia Dortmund two weeks ago.

In team news, Arsenal will be without the injured trio of Theo Walcott, Gervinho and Laurent Koscielny and Andrey Arshavin is likely to come into the XI.

Yossi Benayoun (thigh), Johan Djourou (hamstring), Abou Diaby (ankle) and Thomas Vermaelen (ankle) are all missing too but the big news coming out of North London this week is that England starlet Jack Wilshere will be on the sidelines for another five months after undergoing ankle surgery on Monday.

Kieran Gibbs scored his first goal for the Gunners against Shrewsbury in the Carling Cup last week and may well be picked over fellow left-back Andre Santos.

Olympiakos opted for a 4-5-1 formation in their first Champions League tie of the season and given the fact they are away to a team with such a rich European pedigree, it is likely this tactic will continue.

The Greek side have never gained a single point playing in England and have only found the net once – scored by Brazilian Rivaldo at Anfield in 2004/05.

The Emirates Stadium action kicks off at 19:45 this evening and despite the Gunners’ lengthy injury list, it would be a huge surprise if Arsenal don’t kick off their home Champions League campaign with a victory.
